Dimethicone Crosspolymer
Cross-linked form of dimethicone, a polymer network of siloxane chains. Functions as a thickener, emulsion stabiliser, and texture modifier – providing the characteristic 'silky-powder' feel loved in primers and mattifying bases. Visually fills fine skin irregularities and wrinkles. Non-comedogenic. A common component in blurring effects in sunscreens and foundation bases.
